i found one chord-kbd related article in applied ergonomics (uk)
(1983, 14-1, pp. 55-59).  it reviewed chord kbds and its reference
section contains a few recent papers.

the conclusion is that the main adantages of chord kbd are:

  1. can be operated by one hand.
  2. small size and compactness.

it is mentioned that measuring speed of chord kbds is very hard
since there are few skilled chord keyboarders.

also some chord kbds (including shorthand machines) are fast
partly because they transcribe text into a form of shorthand.
(my interpretation: even with the traditional kbd, if you transcribe
text into a form of shorthand, you can speed up.)

the author was at Loughborough Univ. of Technology (probably in UK?).
please e-mail to me if you know the address of the University.

back to my original question: as far as ordinary text processing is
concerned, it seems that I still cannot find any experimental data showing
that a chord kbd is much faster than the a traditional (sequential) kbd.

thanks.
